The optional full-foam insulation offered in Tropic Seas Spas provides the most efficient heat retention available in any spa on the market. It dramatically increases the strength and life of the spa’s shell. The Icynene brand of full foam secures plumbing to the shell for longer plumbing life and conforms to all curves and spaces to provide a seamless air barrier. Increasing the durability of the structure, the foam provides consistent R-value to the spa. Icynene foam is not water permeable.
It allows structural moisture to diffuse and dissipate and will not trap moisture inside its cells so it dries completely.
*Spas must have Elite Model Upgrade for shipment to CA & CT.
